The net force that must be applied to Jocelyn is 139 Newton.

The net force acting on Jocelyn during the death spiral can be determined using the equation:

F = m * a

where F is the net force, m is her mass (47.3 kg), and a is her centripetal acceleration.

To find the centripetal acceleration, we can use the equation:

a = v^2 / r

where v is her velocity and r is the radius of rotation.

We know that Jocelyn completes one rotation every 1.13 seconds, so we can calculate her velocity:

v = 2 * pi * r / T

where T is the time for one rotation

Plugging in the known values:

v = 2 * pi * 0.915 m / 1.13 s

v = 5.09

Now we can substitute the value of v into the centripetal acceleration equation:

a = v^2 / r

a = 5.09² / 0.915

a = 28.3

F = ma

F = 47.3 × 28.3

F = 1339 Newton

Answer:

Newton (N)

Explanation:

The correct option is C. Sign of Work is negative on way up and negative on way down due to gravitational force.

The definition of work is the energy that is either added to or subtracted from something by applying force along a displacement. For a constant force acting in the same direction as the motion, the work is simply equal to the product of the force's magnitude and the distance travelled.

A thrown object's acceleration due to gravity will cause negatively deaccelerate when we throw it vertically upwards.

We represented deacceleration by a (-) sign.

Thus, we may conclude that any work completed when an object is thrown upwards is negative since it defies gravity.

Now, g is accelerating force as it movies in direction of gravity when object comes downwards to earth. Work done when object moves down is positive.

When solving conservation of motion problems in two dimensions, it is important to break the velocity of each object into x and y component.

Velocity is a vector representation of an object's or particle's displacement with respect to time. The meter per second (m/s) is the standard unit of velocity magnitude (also known as speed). Alternatively, velocity magnitude can be expressed in centimeters per second (cm/s). The direction of movement of the body or item is defined by velocity. Speed is fundamentally a scalar number. Velocity is, in essence, a vector quantity. It is the pace at which distance changes. It is the displacement rate of change. Simply put, velocity is the rate at which something travels in a certain direction. For example, the speed of a car driving north on a highway or the speed of a rocket after launch.

The velocity of the smaller mass just after the collision is B) +0.7 m/s.

To calculate the velocity of the smaller mass after the collision:

Use the law of conservation of momentum, which states that the total momentum before the collision is equal to the total momentum after the collision: (m1 * v1) + (m2 * v2) = (m1 * v1') + (m2 * v2')

Substitute in the known values: (4.0 kg * 0 m/s) + (8.0 kg * 0 m/s) = (4.0 kg * v4) + (8.0 kg * (vg + 3.5 m/s))

Solve for the velocity of the smaller mass (v4): v4 = (8.0 kg * (vg + 3.5 m/s)) / 4.0 kg

Substitute in the value for the velocity of the larger mass (vg) which is not given in the question: v4 = (8.0 kg * (0 m/s + 3.5 m/s)) / 4.0 kg

Solve for the velocity of the smaller mass (v4): v4 = (8.0 kg * 3.5 m/s) / 4.0 kg

Simplify the calculation: v4 = 2.8 m/s / 4.0 kg

Divide the final value by the mass of the smaller object: v4 = 0.7 m/s

So the velocity of the smaller mass just after the collision is 0.7 m/s.

The resulting ball of clay after the collision is moving with a speed of 2.53 m/s in a direction between east and north.

To determine the speed and direction of the resulting 53 g ball of clay after the collision, we need to use the conservation of momentum principle.  

Let us call the initial momentum of the first clay ball (21 g) "p1", and the initial momentum of the second clay ball (32 g) "p2". The final momentum of the resulting clay ball (53 g) will be "p3".

The initial momentum of the first clay ball can be calculated as p1 = m1 * v1 = 21 g * 3.2 m/s = 67.2 gm/s (going east)

The initial momentum of the second clay ball can be calculated as

p2 = m2 * v2 = 32 g * 2.1 m/s = 67.2 gm/s (going north)

So, the total initial momentum is p1 + p2 = 67.2 gm/s + 67.2 gm/s = 134.4 g*m/s

After the collision, the total momentum of the resulting clay ball is 134.4 gm/s, and its mass is 53 g. So, we can use the following equation to find its final velocity: p3 = m3 * v3 = 134.4 gm/s = 53 g * v3

So, the final velocity of the resulting clay ball is v3 = 134.4 g*m/s / 53 g = 2.53 m/s.

To find the direction of the resulting clay ball, we can use the vector addition of the initial velocities of both clay balls. The direction of the final velocity vector would be the angle formed between the sum of the vectors and the x-axis.

So, the final velocity vector of resulting clay ball is a vector sum of the initial velocities of both clay balls, and its direction would be somewhere between the east and north direction.

Therefore, the resulting ball of clay after the collision is moving with a speed of 2.53 m/s in a direction between east and north.

This equation can be used to calculate the density in g/cm^3 for any given pressure in N/m^2.

Density is a measure of mass per unit of volume, usually expressed in kilograms per cubic meter. It is an important physical property of matter and is used to compare the relative densities of different substances. Density is also used to calculate the buoyancy of objects in a fluid. The density of a substance is affected by temperature and pressure. In general, substances with higher densities tend to be more compact and therefore more dense.

A. The units of 70.5 and 8.7 times 10^7 are lbm/ft^3 and lbf/in^2 respectively.

B. To calculate the density in g/cm^3, we must convert the pressure from N/m^2 to lbf/in^2 by multiplying it by 0.2250. Thus, we have 9.0 times 10^6 N/m^2 * 0.2250 = 2.025 times 10^7 lbf/in^2. Plugging this into the equation, we have rho = 70.5exp(8.7 times 10^-7 * 2.025 times 10^7) = 1176.6 g/cm^3.

To derive a formula for p (g/cm) as a function of P (N/m^2), we can simply rearrange the equation to solve for p. Thus, we have p = 70.5exp(8.7 times 10^-7 * P) / 0.002205. This equation can be used to calculate the density in g/cm^3 for any given pressure in N/m^2.

To find the time-domain voltage over the capacitor using phasor domain techniques, we need to first convert the circuit to the phasor domain by replacing the time-varying voltage and current sources with their phasor equivalents. The phasor equivalents of the voltage and current sources are:

V_s = 12 V * e^(j2pift)

I_s = 20mA * e^(j2pift)

where f is the frequency of the sources (1 MHz) and t is time.

The phasor voltage across the capacitor can be found using the following equation:

V_C = V_s - I_s * (R_1 + R_2 + j2pifL) - I_s * (1/(j2pifC))

Substituting in the values for the resistance and reactance of the circuit, we get:

V_C = 12 V * e^(j2pift) - 20mA * e^(j2pift) * (1000 Ohm + 2000 Ohm + j2pi10^620e-6 H) - 20mA * e^(j2pift) * (1/(j2pi10^6200e-12 F))

Simplifying, we get:

V_C = 12 V * e^(j2pift) - 20mA * e^(j2pift) * (3000 Ohm + j40pi) - 20mA * e^(j2pift) * (5e5 Ohm)

So, the phasor voltage across the capacitor is V_C = 12 V * e^(j2pift) - 0.02 A * e^(j2pift) * (3000 Ohm + j40pi) - 0.02 A * e^(j2pift) * (5e5 Ohm)

Finally, to find the time-domain voltage over the capacitor, we need to take the inverse Fourier transform of the phasor voltage. This can be done using the following equation:

v_c(t) = real (V_C * e^(-j2pift))

Substituting in the value for V_C, we get:

v_c(t) = real (12 V * e^(j2pift) - 0.02 A * e^(j2pift) * (3000 Ohm + j40pi) - 0.02 A * e^(j2pift) * (5e5 Ohm)
